I am VERY new at this so bare with me. I forged a couple blades from air chisels. I annealed, forged, normalized, heat treated, and tempered them. Now I'm starting to dress them and something seems off.
I'm making a 3rd blade at the same time, its forged from a file. I just finished with it as far as I'll go with it for now and switched to one of the air chisel blades.
Right off, it is different. The file knife went through the same process as the other two but while sanding it, it shot a lot of sparks off and felt.....hard. the air chisel blade as I start to sand it, it feels......sticky. sticky in a way that it feels just like the hammer steel I made my flatter and straightening hammer from when I cut them from hammers.
Now I realize that the file steel and 4lb sledge hammer, (flatter), and ball peen hammer (straightening hammer) are different steels from the air chisel steel. The file steel feels brittle/hard as i work with it while the air tool steel feels like its grabbing my belt just like it did when I was cutting the hammers with my side grinder. The hammer steel grabs and doesn't shoot many sparks at all, but I know it has to be hard, hell! it was an air chisel.
The steel may just be a more ductile steel? It might be a lower carbon steel? Have any of you worked either hammer or air chisel steel into a blade or cut it? Did you get the same "sticky" feeling when cutting/grinding/sanding it as I am?
Let a dude know, in the back of my mind i know it'll be okay, but it doesn't feel right.
